Alocasia Stingray Care – Light, Water, Potting Soil Mix, Proapgation & Repotting

Last Updated on March 19, 2022 by Admin

The Alocasia Stingray is a rare plant with exotic looks. However, is it easy to care for and you can grow it indoors or outdoors.

Note that if you plant it in the ground outdoors, the plant will grow much bigger than its also large size. It will also look different to one that it grown indoors in a container.

Nevertheless, the plant is beautiful wherever you decide to put it.

Its large green leaves and long stems always make it stand ou.

How to do you care for Alocasia Stingray? Keep the plant in medium to bright, indirect light. Avoid direct sunlight or very strong, intense light. it also enjoys warm, humid conditions.

Make sure to allow the soil to dry between waterings. Also, use well-draining potting soil. This way you avoid possible overwatering or waterlogging.

Alocasia Stingray Plant Care

Light Requirements

The Alocasia Stingray thrives on bright, indirect light. It will also do well in medium light and can tolerate low light.

However, I don’t recommend the latter because past a certain light threshold, the plant will grow slower. It will also produce fewer leaves. And the leaves that you get will be smaller than normal.

As such, you always want to be wary of too little light.

From experience, I’ve found that the term “too little light” means any area where you cannot take out a book or newspaper and start reading it.

In contrast, as long as you an read the small text on books and newspaper in that location without having to turn on a lamp or the ceiling lights, it means that there is enough illumination to keep the plant growing well.

That said, for the best growth, bright, indirect light is still ideal.

On the other hand, also keep the Alocasia Stingray away from direct sunlight.

The plant cannot tolerate more than 2 hours or so of this on a daily basis. Otherwise, its leaves will experience sunburn. And you see brown burn marks on them.

Therefore, the best locations indoors for the plant are near an east or west facing window. If you want to keep it in a southern exposure, distance the plant from the window so that the sun’s rays never touch it.

Outdoors, a spot with partial shade is best. Avoid leaving the plant in full sun.



The Alocasia Stingray is a tropical plant.

This means its preferred climate conditions are warm and humid. Just as importantly, it likes the weather to be somewhat consistently like that even through the end of the year.

This makes its perfect to keep outdoors in USDA Hardiness Zones 8 to 11.

And if you live in there areas, you can leave the plant outside in a pot or plant it in the ground in your garden.

It is worth noting that when grown in the ground, the Alocasia Stingray can grow into a fairly big plant. It will be a bit smaller in a pot outdoors.

However, indoors in a container, the plant’s size will be much smaller than both the outdoor scenarios.

In any case, because the plant enjoys warm weather, its ideal temperature is between 65 and 75 degrees Fahrenheit.

This is where it will grow best.



The Alocasia Stingray is native to the tropical forests of Asia. As such, it not only enjoys warm to hot climates, it also likes high humidity.

In fact, its ideal humidity is between 60% to 70%. Although, it will tolerate as low as 50%.

This can make it somewhat challenging to care for in some homes.

That’s because depending on where you live, the humidity may be a lot lower.

For example, the 3 states with the lowest humidity are New Mexico, Arizona and Nevada. As you can easily see, these are all dessert areas or near-desert locations.

However, the plant will be okay in many other plants.

The best way to tell is to use a hygrometer. This will tell you the humidity in your home or any particular room.

Thus, you know whether or not the moisture in the air is high enough to keep the plant happy.

If not, you’ll eventually see the plant’s leaves turn brown and crispy beginning on the tips and edges.

This is a sign that it needs more humidity.

You can use a humidifier or a pebble tray to increase this level. Alternatively, you can give the plant a shower every 2 weeks or so. This method also clean the leaves to help prevent pests.

Misting can work as well, but I don’t recommend it.

For one, you need to keep doing it over and over since the effects are temporary. Also, if you mist too much or later in the day and the moisture on the foliage does not dry, it can cause fungal infections in the long run.

So, the extra work and risk are just not worth it for me.




How Often to Water Alocasia Stingray

The Alocasia Stingray has moderate watering needs.

Outdoors, this means about an inch of rain every week. So, if you don’t get enough rain, you can supplement by adding water as well.

And while the plant likes to stay in moist soil, it is important to let the soil dry between waterings.

The reason is that too much water is harmful to the plant.

Overwatering can lead to root rot, which can ultimately destroy this beautiful plant. So, avoid this issue at all costs.

The best way to do so is to allow the top 2 inches of soil to dry between waterings. You can wait a little longer as well. It does not need to be precise.

However, avoid watering before you feel that the soil in the top 2 inches is dry to the touch.

Following this simple rule and making sure to check the soil each time before you water will save you the headache of having to deal with overwatering in the future.

One of the best things about this method is it will automatically adjust as the seasons change.

During summer, as the weather gets much hotter, the soil will dry sooner.

So, you may find yourself watering every 3 or 4 days instead of once a week.

And in the winter, the frequency will automatically decrease as the cold weather will keep soil wet and moist longer. This can mean watering once every 2 weeks.


Alocasia Stingray Potting Soil

The best soil for Alocasia Stingray is loose, well-draining and airy. This will allow the roots to get water but not too much. It will also allow them to get enough oxygen to stay healthy.

In contrast, you want to avoid heavy soils, dense or compact ones as well. Any other soil that tends to retain water or a good amount of it is also not ideal for this plant.

Although these may work for other plants, it will put your Alocasia Stingray at risk of overwatering and waterlogging.

Instead, always make sure there is sufficient drainage.

The easiest way to get this kind of soil is to mix:

  • 1 part potting soil
  • 1 part peat
  • 1 part perlite or coarse sand

The perlite will provide sufficient drainage to prevent overwatering and the soil from getting waterlogged.

In addition to using the right kind of soil for the plant, it is also important to use a pot with drainage holes.

This will allow the excess liquid that drains from the soil to exit the container.

Otherwise, the excess water will just pool at the bottom of the pot and keep the soil wet.



The Alocasia Stingray has a good appetite. Therefore, it does enjoy fertilizer. And giving it these nutrients will allow it to grow bigger, faster. It also let the plant produce more foliage and large ones at that.

To make sure the plant grows optimally, feed it with a liquid fertilizer. I like to use a balanced formulation. This ensures there is a good amount of nitrogen to fuel foliage development.

Once a month feeding during its growing season in spring and summer is best.

It will grow the fastest during this time.

Don’t feed it in the fall and winter.



The Alocasia Stingray will grow into a big plant. Outdoors, it will reach 15 feet tall with long stems and large leaves split apart. This makes it stunning to look at.

While it won’t grow as big in a pot, it will still reach a good medium size.

Its leaves also way veer as far away from one another. And it you let get bushy, it will look very impressive in your living room or patio.

Its large laves and many long upward curving stems are the most beautiful parts of the plant.

And I encourage you to let them grow and get bushy.

That said, there will come a point where you will need to prune it to maintain its looks. For come growers, they’ll prune it to limit its size and width.

How much you prune will depend on how big you want to maintain the plant. And how much foliage you want.

But in general, this is a low maintenance plant as far as pruning goes.


How to Propagate Alocasia Stingray

The simplest way to propagate the Alocasia Stingray is by rhizome division. Although there are a few other methods you can using including propagation from seeds, offsets or cutting root stems.

To propagate the Alocasia Stingray by rhizome division, you’ll need to unpot the plant.

Therefore, it is a good idea to have a potting table or a space where you can work.

If you use the floor of your home indoors, make sure to cover it first with old newspapers or plastic. That way, it is easy to clean up after.

The first step once you have your workspace ready is to unpot the plant.

Brush off the excess soil to see the roots clearly. Alternatively you can run water through the excess soil to wash it away. This will leave you with the roots.

If you used water, allow the roots to dry first before you continue.

In some cases, you may see offshoots growing. You can use these if you want. But since they are unpredictable when they will appear, they’re not the more practical way to propagate the plant.

Instead, we’ll be dividing the rhizome.

Next, check and decide which sections you want to divide. Make sure each section has stems and leaves above as well as roots. They will not survive without corresponding roots.

Once you’ve decided on the division, take a sterilized knife and cut the rhizome into the divisions you desire.

Plant each of the divisions into their own pots with fresh potting soil.

In about a couple of months, you should see new shoots growing.


How to Repot or Transplant Alocasia Stingray

The Alocasia Stingray only needs repotting once every 2 years.

Do note that if you have a young plant, you’ll need to repot more often as it will grow bigger faster. But once the plant matures, the root system will take a bit longer to grow before it requires repotting.

The best way to tell when to repot is to check the bottom of the pot.

If you see roots peeking out from the drainage holes, that means the plant wants to move to a bigger home.

Another sign that your Alocasia Stingray has outgrown its pot when you see roots on the surface of  the soil.

in either case, be ready to repot.

The best time to repot is spring. You can also do it early summer.

Use a pot that is one size larger and replace the soil as well.


Is It Toxic/Poisonous to Humans, Cats & Dogs

Yes, the Alocasia Stingray is toxic. This is true for both humans and pets. Although the plant only becomes toxic when ingested. So, avoid leaving young children, dogs or cats near the plant to reduce the risk of accidental consumption.


Alocasia Stingray Problems & Troubleshooting


The Alocasia Stingray can experience mealybugs, spider mites, aphids and scale. Although it is fairly resistant to them when healthy.

Thus, it is very important to keep the plant in good health.

On the other hand, if it is stressed, weak or sick, it becomes susceptible to these bugs.



Root rot and leaf spot are two common problems you want to watch out for.

Rotting happens due to overwatering in soil. When you add too much water, it can drown the roots and suffocate them causing root rot.

On the other hand, wet leaves that don’t dry lead to leaf spot.

Thus, avoid watering at night, over misting the plant or placing it somewhere with little light or airflow. The latter will prevent moisture from quickly drying.
